DAVID LIPPY, OF MANSFIELD, OHIO.

MEAT-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 599,569, dated February22, 1898.

Application filed January 11, 1897. Serial No. 618,851. (No model.)

To all whom t may concern:

Be it known that I, DAvID Lrrrv, a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio,haveinvented certain new and useful Improvements in Meat-Sawing Machines;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

My invention relates to improvements in meat-sawing machines; and theobjects of my invention are, rst, to construct amachine for sawing meatwith a circular saw and to obviate the necessity of using a knife andsaw,

which are now in common use in all butchering establishments; second, torotate a circular saw by a combination of pulleys and belts to be usedin slicing meat; third, to construct the top of the table so that it canbe rotated at the will of the operator; also, to divide the top intoseparate platforms, each part provided with rollers, ratchet mechanismfor operating the rollers, and a clamping device for holding the meat inposition, each platform can be used for different kinds of meat; fourth,to make a cheap, durable, and efficient means for thepurpose stated. Iattain these objects by the mechanism illustrated in the accompanyingdrawings.

This application is one of a series filed by me of even date herewithfor improvements in meat-sawin g machines and bearing, respectively, theSerial Nos. 618,852 and 618,853.

Figure l is a side elevation of my improved meat-sawing machine, showingthe general construction of `all the' parts embodying my invention. Fig.2 is a top view of same, showing more fully the circular platform, therollers in each division of the same, the clamping device, ratchetmechanism, and combination of pulleys and belts composing the motor.Fig. 3 is a transverse sectional View of circular platform, the modeofpivoting the same in the top of the machine-frame, and theantifriction-rollers, upon which rests the platform. Fig. et is a frontview of hand-lever,showing its general construct-ion. Fig.

5 is a'side elevation showing a different motor than the one shown inFig. 1, the saw operating on parallel guides, the guides and saw adaptedto be raised vertically when not in use Fig. 6, a top view of same. Fig.7 is a front view of lever, showing the mode of at- Jcaching the same atits lower end to the framesill. I have shown this device as amodification of Fig. l. p

Similar letters refer to similar parts throughout the several views.

In the accompanying drawings, A indicates the frame of the machine,which is composed of the legs B B, upper rails C, top D, and sills E.These constitute the frame of the machine.

' F indicates the circular platform; G, the metal pivot-pin, which issecured in the center and upon the under side of the platform. Asuitable boxing H is placed in the top D and in which is pivoted theplatform F. The

said platform is provided with the metal angle-irons I, so arranged uponthe platform that they form recesses J. Each recess is provided with therollers K, K', and K2. Each roller is journaled in bearings made in theedge of the angle-irons to hold them in position. The roller K' isprovided upon one end with a ratchet-wheel L, lever N provided with thepawl N to manipulate the roller. The clamping deviceis composed of theL- shaped bar O, hinged upon its lower end to the angle-iron I. Theunder side of the horizontal'arm is provided with pointed projections P.The vertical lever Q is also hinged at its lower endy to the angle-ironI upon the opposite side of the platform and is provided with notches Rto engage the bar O. Each set of rollers is provided with the clampingdevice and ratchet mechanism. This description is fully shown in Figs.1, 2, and 3.

The locking device to hold the platform from rotating is composed of thelever S, placed under the top of the frame and in a line with the centerof the circular platform. One end is hinged tothe side rail D of theframe A, the loose end of the lever passing through the rail upon theopposite side of the frame. An upwardly-projecting pin T is secured inthe edge of the said lever, the said pin passing through a hole made inthe top 0f Athe table and engaging the under side of the circularvplatform. The platform rests upon antifriction-rollers U, secured in thetop IOO of the frame. Upon one side of the frame and near the end isbolted the standard V. A suitable box-bearing YV is cast in the same andin which is placed a suitable shaft X. Upon the said shaft are securedthe pulley Y and balance-wheel Z, provided with the handle B'.

C indicates a bifurcated lever. The lower ends are pivoted upon theshaft D, the said shaft having a bearing in the boxing E', secured uponthe outwardly-projecting end of the sill E.

F is a pulley secured upon the shaft D between the boxand one arm of thelever. There is also a pulley G secured upon the said shaft upon theoutside of the lever. Two pulleys H and I are secured upon the shaft J',the said shaft journaled in each bar forming the bifurcated lever andnear the upper end of the same.

K2 indicates round metal guide-rods. The said rods are placed insuitable bearings formed in the top of the standard V. One end of eachis secured in the plates L L, located on each side of the lever. Theinner ends are secured in the cross-head M. The said crossheadisbifurcated and is provided withasaw N2, saw-1n andrel O, and pulley P.The pulley is placed within the bifurcation formed in the cross-head.

Vhen the lever C' is placed in position, the pulleys Y and G are in lineand provided with a belt Q. The pulleys F and I are also in line;also,the pulleys P and H. Each pair of pulleys is provided with suitablebelts R and S to connect the same.

It will be readily seen by those skilled in the art that when theoperator takes hold of the handle B and rotates the wheel Z motion isconveyed to the shaft and pulleys D, F, and G' through the belt Q. It isalso conveyed to the pulleys Il and I' through the belt R and to the sawN through the belt S.

Then the operator wishes to cut meat, he places a joint upon one set ofthe rollers and then feeds it forward by the ratchet mechanism until asufcient quantity of the meat projects past the saw. It is then heldfirmly by the clamp-levers O and Q. Ile then rotates the saw by themechanism described and then forces the saw through the meat and bone bythe lever C'. As soon as the operator releases the lever it returns toits normal position by the action of the spring T. This description isfully illustrated in the sheet of drawings marked Plate l.

The sheet of drawings marked Plate 2 is shown as a modification of Fig.l, Plate 1, the frame and platform being the same as described. Theparticular change is in the crosshead and guides and mode of belting.Where three are used in the description given above, two only are usedin this device. The crosshead A2 is placed upon the two parallel guidesB2. The inner ends are pivoted upon each side of the standard C2. One ofthe guides is provided with a vertical lever D2, having a spring-boltfastener E2, which engages in suitable notches formed in the top of thestandard C2.

F2indicates connecting-rods, the outer ends secured in lugs formed uponthe top of the cross-head, the inner ends to the lever G2.

H2 indicates a foot or support secured upon the outer ends of theguide-rods, and when in position, as shown, the foot rests upon the topof the table I2 to hold the guide-rods parallel with the top of theframe A2.

J2 indicates a belt which passes around the mandrel-pulley K2, thenceover the pulley L2, then downward around the pulley N2, up over thepulley M2, forming a communication from one to the other. Bypullingdownward upon the lever D2 the guides, foot, and saw are raisedin a vertical position to allow the operator to place meat upon theplatform.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
